Tip: I can’t stress enough how important it is to tilt the jar and pour slow. Then carefully pour the red liquid into the tall jar. Add a few drops of red food coloring to 1/4 cup of rubbing alcohol and mix until combined.Make sure to tilt the jar and pour very slowly so the colors don’t mix. Tip: Again, be very careful when pouring in the liquid. Wait a few moments and then slowly pour 1/4 cup of olive oil into the jar.
Tip: When pouring in the green liquid, tilt the jar so the liquid runs down the side of the jar slowly. Then carefully pour the green liquid into the tall jar. Then add a few drops of green food coloring to 1/4 cup of water and mix until combined.Next add about 1/4 cup of blue dish soap to the tall jar.Pour the purple liquid carefully into the tall jar. Add one drop of red food coloring and one drop of blue food coloring to 1/4 cup of honey and stir until combined.Objects will sink in water if their density is greater than 1 g/mL.
Objects will float in water if their density is less than 1 g/mL. Liquids with a lower density will always float on top of liquids with a higher density.Īll liquids have their own unique density. Because olive oil and rubbing alcohol are less dense, they will float on top of liquids like water, dish soap, and honey. Lighter liquids (like olive oil and rubbing alcohol) are less dense than heavier liquids (like honey and dish soap) because they have less matter in a given volume. Density is all about how tightly packed the matter making up the material is in a given volume. Also, if mass decreases but the volume stays constant, then the density decreases. Density is a ratio of mass to volume and can be found by dividing an object’s mass by its volume (D=m/v).īased on this equation, if the mass of something increases but the volume stays constant, then the density increases. Video Tutorialĭetailed Rainbow in a Jar Science Experiment Step by Step Instructions How Does the Science Experiment Workĭensity is the reason that this experiment works! Density is a measure of how much mass (or “stuff”) there is in a given volume. Otherwise, the colors will mix together and you won’t get a distinct rainbow.ĭo you know why you were able to make the liquids form the rainbow in a jar? Find out the answer in the how does this experiment work section below. Then, carefully pour the red liquid into the tall jar. Step 5 – Add a few drops of red food coloring to 1/4 cup of rubbing alcohol and mix until combined.
